Intro/Set Up
For this creative assignment, I was interested in looking at datasets from Chicago First I loaded relevant r libraries as well as other r libraries that might be useful to me later on and pulled a world map using the libraries loaded below.
library(osmdata)
library(opentripplanner)
library(tidyverse)
library(sf)
library(ggthemes)
library(ggspatial)
library(sp)
library(stringr)
library(rgeos)
library(tidygeocoder)dcfarmersmarkets<- st_read(
"https://opendata.arcgis.com/datasets/f2e1c2ef9eb44f2899f4a310a80ecec9_2.kml")## Reading layer `Farmers_Market_Locations' from data source `https://opendata.arcgis.com/datasets/f2e1c2ef9eb44f2899f4a310a80ecec9_2.kml' using driver `KML'
